Breast cancer is a worldwide physical condition load through over one million novel cases identified universal and over than 250,000 novel cases identified in U.S. each year. The early stage of the disease without a prior diagnosis 2 Metastatic Breast Cancer (MBC), with approximately one-third of women, despite the locoregional therapy and adjuvant chemotherapy, fur thermore United States.2 all new breast cancer represents approximately 5% of early stage breast cancer will experience a distant relapse. As a result, the United States, more than 40,000 deaths each year are related to breast cancer. MBC associ-ated median survival of only 2 to 3 years of treatment is a likely outcome, investigators disease specific optimization results, ideally, prevent or relieve symptoms associated with cancer and quality of life by try to improve results. The most important of these efforts, scheduling, recent therapeutic innovations in drug delivery, resulting in a large number, and targeted therapy. INNO-vations of the current speed of their treatment, however, grown ingly complex clinical decision is made. Strategy has not been determined, although ideal, several general management Ment MBC rationale for the strategy will be reviewed here.
Improved survival in MBC
Within the past 2 decades, MBC management eg taxanes, vinorelbine (Navelbine, GlaxoSmithKline), gemcitabine (Gemzar, Lilly), and capecitabine (Xeloda, ROCHE's) with the introduction of new systemic agents have been developed, the third generation of aromatase inhibitors (ALS), including the new hormonal agents and trastuzumab (Herceptin, a Genentech), bevacizumab (Avastin, a Genentech), and lapatinib (Tykerb, GlaxoSmithKline) including biological treatment. MBC during the past few decades, improvements in survival have been described, although these improvements can be attributed directly to innovation thyra- peutic 3 • 4 held in British Columbia only conclusive evidence of a large population-based retro-spective analysis is from. 5 MBC investigators aged 75 or younger at the time of diagnosis to treatment for women with results reported by far. The cohort of women diagnosed between 1991 and 1992 in the median survival of 14.3 months, compared with a small profit from 1994 to 1995 of paclitaxel and vinorelbine Introduction- duction, docetaxel 18.5 months with the introduction of further improvements from 1997 to 1998, and was celebrated with ALS, and 2001 (Table 1) in 1999 with the introduction of capecitabine and trastuzumab is a significant improvement of 21.7 months. However, treatment of MBC INNO-vation and improvement in survival, methodologic limitations of a retrospective analysis of all subgroups benefited from these innovations is the possibility that the relationship between the opti wealth management paradigm MBC is an ongoing controversy about has resulted. Principles of treatment of women with MBC MBC a consensus algorithm for the management, administration appropriately MBC Ment strategy a number of patient and tumor characteristics (Figure 1) can be determined by considering.

Formulate a cure when disease-free interval, prior adjuvant therapy prescription, metastatic sites, number of visceral crisis, age of the patient, like the patient, comorbidities, performance status, hormone receptor status, HER2 status and the ability to be considered strategy should be. In gener al, the efficacy, favorable side effect profile, and general ease of administration, endocrine therapy are at risk for visceral crisis which is better for women with hormone-responsive MBC. Systemic chemotherapy is usually refractory to hormonal dis-ease, for women with hormone receptor-negative disease, safe, and viscer Al metastases rapidly progressive and / or symptomatic women are selected. All women with HER2-positive MBC in the absence of any clear contraindication as part of their prescription systemic chemotherapy should receive trastuzumab. However, trastuzumab-to Progressive disease (see page 24 for further discussion) should be continued beyond the evidence is clear and consistent. Systemic chemotherapy with combination hormone therapy is no evidence to date. More than 6, a continuous treatment schedule management still popular clinical practice, this approach involves a short period after treatment is stopped and an interrupted schedule under which, compared with the survival there is no evidence that translate into improved disease progression resume. An interrupted view of the population in the palliative treatment of a "drug holiday" provided additional benefit. However, continuous or intermittent treat-ment of the benefits of education are generally limited izability more specific drugs might.
Endocrine therapy of endocrine therapy (Table 2) for decades for women with hormone-responsive MBC treatment paradigm is based. Hormone therapy Hormone Responsive MBC, an appropriate disease-free interval, minimal signs of breast cancer, significant disease burden, and visceral crisis with minimal or no risk is appropriate for women. A final strategy is largely determined by the patient's menopausal status are.

".22.23 Consequently, we alone as first line therapy in this population are in favor of tamoxifen. ALS peripheral conversion of estrogen to inhibit steroid ingredients and do not interfere with the synthesis of ovarian estrogen, premenopausal women alone is not suitable for the therapy. Furthermore, premenopausal women, the hypothalamus and pituitary gonadotropin secretion of estrogen, low feedback, and thus increases the detrimental effect of inducing ovarian stimulation. A priest and the population of a GnRH agonist in combination with any level of evidence.
premenopausal women with MBC resistant to tamox-ifen line level to guide treatment decisions, there is a lack of evidence. However, no contraindication to hormone therapy for women with ovarian suppression alone appropriate options, medical or surgical ovarian suppression, megestrol acetate, or in combination with systemic chemotherapy, "pure" is the antiestrogen fulvestrant (Faslodex, AstraZeneca), a Al said.
Postmenopausal
The third generation of ALS, the Letrozole (Femara, Novartis), anastrozole (Arimidex, AstraZeneca), and exemestane (Aromasin, Pfizer), at least Postmenopausal women with hormone-responsive MBC tamoxifen for first-line treatment as efficacious (Table 3). 12-16 No survival benefit has been demonstrated with the strategy, ALS, or more generally the bid of more than 1 year of adjuvant Postmenopausal women who have relapsed after the admini-stration of the first line of tamoxifen is used in the low incidence of thromboembolic events. It was a great, head-to-head for the date comparison of Als in the environment, and the trial on the cross parasons com should be discouraged.
However, many clanacans (see page 16) and the second line therapy now in the environment strwadal Imam amestni vs foloestrant a large clinical trial to review with this latest report is the first line treatment with non-steroidal Imam resulted in a gift. Adjawant Al-Awad, the sickness occurs within 1 year of the Administration, however, are reasonable treatment options tmosevan or foloestrant therapy with the power equivalent to a second-line endocrine therapy equivalent to 1.17 tria rndomaid demo recently performed as one force was recently report-Ed rndomaid 2nd line foloestrant or amestni case (anstrosoli or letrosoli) is a non-steroidal Imam after first line therapy (MIG) with equal Anstrosoli tmosevan foloestrant or other power line MBC-resistant 19.2 ° in phase 2 trials in women with sick, even though there was no demonstrated after the strategy detailed aopata MAL have been clearly, in an appropriate manner in the appropriate manipolatance additional hormonal treatment options-, tmosevan-, and foloes-trant-resistant is the patient.

Breast cancer is one of the most sensitive tumor chemotherapy.
The most severe reaction rates atbek rigamance antrikiclana or tagsina stratad in dev-setting Are with contain. However, given that many women have a total of adjawant antrakiclan and kardaotisati antrikiclana Thera advance Australia III, received a tagsina rigamance with risk the first line point of view emerged as a favorite as well. As a result, investigators tagsina on rigamance innovation based on scheduling and delivery to improve with Yes. For example, the improved response rate and TTP paclanal q3weekly compared with traditional weekly report with a regimen is found."Nnoparticali alboman carrying paclanal (NAB-paclanal abraxani, abrukss baaskinse tagsina is a remarkable innovation in delivery;), which is not associated with the traditional tagsina hiprsansatawati reaction solvent and therefore do not need steroid primadikon. Tagsina strategies6 paclanal NAB at least as efficacious as the traditional "add 5 more of the active agent only NAB paclanal activity or partially allow for delivery from krimovaor preparation, but also may not reflect the postolatad for alboman paclanal to the preferred delivery of cancer cells is reflected. Seems to be an ideal second line as the first line in an atmosphere of antrikiclana-pritritad tagsina-resistant atbek strategy has been determined, still not. Tagsina-antreci-atbek-rigamance and the cowl on most in an atmosphere of consensus exists, the holder of a kombana during a single agent treatment chemotherapy strategy versus taon-respectively the main conflict persists. Many clanacans a point of view, the only agent manamyazaon serial palliatowi treatment for the patients, the survival benefit in toxicity with duo strategy and disease development is the active agent the opportunity to secure a broader weapons continue to be a lack of evidence, citing is the most precious gift. One by one, other clanacans combination approach, CIT-a demand for better command — typically the first reaction rate or time in large clinical trials and development (see Figure 2) – rndomaid most active agents in the treatment of the skin when a patient's toxicity and treatment-resistant clones may be tolerance mksmal stop Given that the benefit of administering the ideological fight. Although both have sound evidence, it can be compared with the respectively single agent strategies reviewed the history collection with no clear strategy for sustainable benefits, and performed the same is important to remember. Moreover, the recent improvement in the treatment baalogak tularatad relatively well, with strong, traditional, possibly diminishing the role of potentially toxic or rigamance to change. Ioatad sanglat vs aiwal this study selected pair are presented in table 6 the strategy?
Targeted therapy atbek treatment samples recently targeted agents baalogak/treatment strategy has become one with the incorporation of ancres finger complex. Trastosomab, lapetanab, and bevakyazmab forms here including com baalogak will be reviewed Monday to treat.
Trastosomab approximately 20% to 30% of breast cancer HER2, which all human silictaoli manklonal trastosomab of the antibody has been targeted by a transmimberani glkoprotian aoorexpress-tyrosine canasi activity. Monotropi atbek Hardy trastosomab in patients of chemotherapy in early education, about 12-15% response rate for the first-line HER2-positive 7 ° trastosomab monotropi atbek .69 reported, with one of the women in the study, 35 percent rate, were later re-sponse .71 reported this impressive response rate and General tularablati trastosomab kitotosack trastosomab cases were given the traditional therapy in combination with agents was for review. The most important phase III trial kitotosack the first line chemotherapy in women with HER2 positive trastosomab with or without atbek 469 randomized.59 women who had received the first antrikiclana with or without paclanal trastosomab went to domaid-ran, while women who had not received the first antrikiclana adremican caklovosfamadi rndomaid aparapan with or without trastosomab, and went to/. In addition, better overall trastosomab-mants was associated with Tehreek-e-Taliban Pakistan (budget deficit rising to seven months versus 7.4. P 0.001 [Figure 2]), objective response < rate (50% versus 32%, P < 0.001), (9.1 versus 6.1 months; duration of response P < 0.001) and overall survival (OS) (20.3 months versus 25.1. P = 0.After the trastosomab, although dokitonal, 046). effectiveness of kapikatbani and oanorelbni, including a large number of agents was investigated, in combination with tagsina-trastosomab education rndomaid stage in the most massive collection of evils has been reviewed. Compounds antrikiclana-trastosomab, al-though the cardiac mitstetak kardaotisati rate to 27% in setting the height as they usually associated with HER2-positive women with atbek trastosomab aovadadn so far for treatment is an essential ingredient of the strategy and when chemotherapy indicates that it is: Kombana-first line therapy in this population with paclanal taon as are should be considered. First line therapy in postmanopasal women with or without estrogen anstrosoli power factor receptor HER2 positive atbek of positive as well as trastosomab which was recently aoallot-free survival (f) collection development degradation associated with significant improvement (4.8 vs. 2.4 months. P = 0.0016) and 27.9% versus clinical benefit rate (42.7. P = 0.026). There is no significant improvement in OS (243.5 vs 23.9 months. P = 0.325) was observed. However, 70% (73/104) in patients with anstrosoli arm trastoso atab his disease during the course of the years.
This targeted therapy to treat well the fawan tularatad-datance represents the current trend to add to a biological agent, in combination with the first line is read the first hormone therapy were reported. However, this data, clinical application is still delayed the stert ayaji trastosomab (Imam only after development administered on) has been the most important, and not in comparison with the fact there are several boundaries. And finally, this study, in which most patients receive adjawant Als relevance of a new era is uncertain. Another important clinical question is: trustee.
Lapatinib
HER1 and HER2-tyrosine anabatr, aoorexpresang lapetanab, a cancer HER2 canasi, a new treatment option for women with HIV and other sexually transmitted diseases. Effectiveness and kapikatbani with or without lapetanab security was reviewed recently by a large random case antrikiclana-tagsina trastosomab pritritad MBC74 14ER2 with women, and positive-399 patients were recently updated in the middle of an independent Review Committee in the analysis of power, by the way, the ratio was 0.57 versus 18.6 weeks tip 27.1 (risk; P = 0.00013) collection (table 7; right, Figure 2). "these results, based on lapetanab recently the food and drug administration of the United States (FDA) was approved for use in this environment. The recommended dosage of lapetanab 1,Kapikatbani 250 mg orally every day for 21 days in combination with 2000 g/m2 per day in a cycle of 21 days 1 to 14 (approximately 12 hours apart in 2 k administered orally) is administered during the day. Clinical trials to treat other targeted, including th bevakyazmab lapetanab in combination with other agents, as the investigation is ongoing. For bevakyazmab angaognisas is an integral part of the development of antiangaoganak Thera, malag n (normal) tissue-Australia was an active area of investigation. Bevakyazmab manklonal a humanized antibody to target and vascular andotalal growth factor (or vigf) bevakyazmab pritritad atbek paclanal now, the most potent and specific in heavy patients (table 7) in combination with the first line therapy has been determined as angaoganak factors indicate that is bound. In an atmosphere of the first line, Kombana paclanal and bevakyazmab the rate of 29.9% (versus 12.8 response taon% was associated with improvement in matak; P 0.0001) and f (that 11.4 versus 6.1 months <.

As a result, important innovations in treatment over the past several decades, women within the main benefits is that the result in survival with atbek.

However, that don't have their own specific sets of women was ideal is for treats. Hormone growth factor receptor positive dis-maniovers for the appropriate candidate with ease are the basis of hormonal treatment strategy. When chemotherapy patients, indicates that it is the first antrakiclan and tgsanas represent the most active agents in secret. Profiles of major symptoms or oaskar, however, for those at risk of the crisis can be considered for patients with normal rigamance and tularatad as well as kitotosack duo with toxicity in the compromised quality of life generally, non-population, respectively Policaimotropi rigamance rigamance or single agent with the ability for survival as a result of the lack of benefits of combination chemotherapy may be indicated. HER2 positive disease to identify all women with trastosomab, but its use is controversial ahead of development. Tagsina trastosomab pritritad antrikiclana them lapetanab kapikatbani-and patients, Al, in combination with the now FDA approved and should be considered. Vigf anabatr bevakyazmab atbek is under investigation for the treatment of promising results are shown. It physiology of breast cancer has been extended an invitation in the future, our understanding of an individual's biology of cancer quickly mant strategy would be appropriate for that was. As clinical trials designed to speed the development of drugs traditionally can exceed the capacity of a new type of challenge but it will represent. For the development of novel drugs for the population from the perspective of survival benefits may need to translate progress in biology.
